    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

  • Returning Visitors

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

Having a problem with lose of power on # 4cyl. when bike warms up 10 miles or so, almost acts like plug fouling, but its clean, we found that the valve ajustment its a little tight cannot slide a 1 1/2 measuring tool under it, could the valves not be closing all the way when hot, but when cold, it is. Compression is 120 when cold 60 Hot, Spark seems good, shims are already 2.50mm range do I still have some room to change to smaller ones or are valves getting time to replace? Thanks
 
They make shims down to 2.0mm. That sounds like it is your problem, if the compression actually drops when it's hot....

Good for you catching it now, burnt valves would be along soon if you were to let it go.

Hi Mr. Larnold6474,

I guess you should start with a compression check. Then do all of the required maintenance. See the lists in your "mega-welcome" below. :)

Let me dump a TON of information on you and share some GS lovin'. :D

I just stopped by to welcome you to the forum in my own, special way.

It sounds less like the valve itself than the adjustment

If you need a thinner shim and can't buy one or get one, the shim club can make you one
 
1 1/2 thousands feelers gauge that the smallest one I had to try, Thanks for all the info will try new shims in a week or so, let you know how it goes
 
It would be a lot easier Larnold if you could post it in the decimal format (.0015") as it's actually printed on your gauge so it's easier to understand. Plus a lot of us use the metric equivalents when working on our bikes (.03mm - .08mm)
